A sniff of hope for people with damaged smelling capabilities

  • There have been few treatments for the condition of the loss of the sense of smelling.
  • There is now hope that a long-established asthma drug may help to restore one's smelling.
  • Research has shown that levels of two proteins in the nasal lining, called cAMP and cGMP , are low in people with hyposmia.
  • Some people have received various doses of theophylline, a drug used to treat asthma, which is known to inhibit the breakdown of cAMP and cGMP.
  • At the end of the treatment, 70 percent of the people with hyposmia had an improved sense of smelling, according to standard tests.
  • The improvements disappeared when people stopped taking the drug.
  • Hyposmia affects around 20 million people in the U.S. alone.
  • It can be started by allergies, viral infections, and head injuries.
